Smokeless Tobacco

Also known as "snuff", "spit" or chewing tobacco, smokeless tobacco is held in the mouth between the teeth and cheek. Users spit out a black, tarry substance that forms when the tobacco combines with saliva. It is absorbed rapidly into the bloodstream through the lining of the mouth making it more addictive than smoking cigarettes.

Users of chewing tobacco suffer permanent gum and bone loss, unlike users of smoking tobacco who usually recover the loss after quitting. Smokeless tobacco is associated with professional sports but has increased in popularity, particularly among teenagers.

How to Quit

Talk to your dentist and your doctor about developing a strategy to quit

Have your dentist screen you for early signs of oral cancer and periodontal disease

Anticipate triggers to using chewing tobacco and prepare strategies to avoid them.

Reward yourself for reaching small goals — go out for dinner or buy yourself a gift

Chew sugarless gum and drink water when cravings hit

Incorporate exercise into your weekly routine

To help prevent or reverse the risks, eat a healthy diet with lots of fruits and vegetables

After: After quitting and a thorough cleaning, this smoker's teeth were restored to their original whiteness. Failure to remain tobacco-free will cause the staining to recur in weeks.
